At first I wondered why anyone should be bothered by this (not being a KISS fan it was just kind of a *shrug* to me). So I'm trying to personalize it a little more.

How would I feel if Rush got a new drummer? And then a new bass player two years later? And then later a new guitarist a year after that? And these three imposter wannabes kept on touring and recording as Rush?

Well... I can't predict how I'd feel. By their fruits ye shall know them. If these guys somehow kept the spirit alive and they actually felt like Rush when they played, I'd probably enjoy them and be fine (though always pining for the "good old days" of Rush like I already do ). But it would likely come down to the music for me.

I remember when the Drama album was released as a YES album and Trevor Horn was singing on it instead of Jon Anderson, it just felt all wrong. The spirit (or soul) of the band just wasn't there. It was a good album, but it didn't feel like YES at all and I thought it should have been called something other than YES. But there might be a singer out there that could keep the spirit of Jon Anderson. Who knows?

The other one I think of is Genesis. Though with them, it wasn't new members... it was members leaving and not being replaced (except for touring). When Peter Gabriel left after the 1975 tour they changed, but only a little. The two albums they released in 1976 were tremendous and still felt like Genesis.

When Steve Hackett left they felt just a a little less like Genesis, but still made two good albums. But the Duke album in 1980 was the begininning of the end, probably because it had a big hit single in the US. After that and the success of Phil Collins first solo album, the stuff they put out didn't feel much like Genesis anymore.
